Smoking pipe



Oct. 14, 1941. RH. SHERLOCK 2,258,867" SMOKING PIPE Filed Sept. 16, 1940 Patented Oct. 14, 1941 UNETED QFHQE 8 Claims.

My invention relates to pipes designed and from the cartridges.

A further object is to provide plungers normally providing seats at the bottoms of the sockets for the inserted cartridges and which are 'shiftable from the exterior of the bottom of the bowl for ejecting the cartridge butts or remains after smoking of the pipe.

Another object is to provide an arrangement with which, instead of smoking a comparatively long cartridge from which the ashes may drop without being caught, two cartridges of half the length may be inserted side by side in the sockets provided in the pipe bowl so that the ashes dropping ,therefrom will be caught by the surrounding bowl, and the two cartridges may be smoked in parallel for greater smoke volume through the pipe stem.

Still another object is to provide construction and arrangement which will enable the pipe parts to be economically manufactured and assembled so that the pipe may be sold at a comparatively small cost.

My invention also involves other features of construction and arrangement and all the features are embodied in the structure shown on the drawing, in which drawing Figure l is a plan view of the pipe;

Figure 2 is a section on plane IIII of Figure 1;

Figure 3 is a section on plane IIIIII of Figure 2;

Figure 4 is an enlarged plan view of the ejector structure; and

Figure 5 is a side elevation of the structure shown on Figure 4.

The pipe shown comprises a bowl I!) having the stem ll extending therefrom for receiving a detachable mouthpiece l 2. any desired shape, the drawing showing it to be of elliptical cross section with the major axis paralleling the stem.

Intermediate the top and bottom of the bowl an annular internal shoulder 13 is provided for The bowl may be of supporting the cartridge holding element. This holding element comprises the body It from whose upper end extends the flange I 5 of elliptical shape to intimately fit against the bowl sides above the shoulder l3.and to rest on the shoulder. Screws l6 extend through and downwardly from the opposite ends of the flange and thread into the bottom wall I! of the bowl so that the holder element is securely held against the shoulder IS.

The body M of the holder element has .two cylindrical passageways I8 therethrough laterally spaced a distance from each other and of a diameter for receiving the ends of tobacco cartridges I9 for supporting these cartridges vertically within the bowl wall above the holder element. .The space 2|] between the holder element and the bowl bottom ll forms a suction chamber communicating with thec stem structure passageway which includes the bore 2| through the stem part II and the bore 22 through the mouthpiece l2, suction at the end of the mouthpiece thus creating suction in the chamber which is applied to the ends of the tobacco cartridges in the sockets l8 for smoking of these cartridges.

The ejector element 23 is in the form of a plate "extending across the bottom of the bowl and having upwardly extending plungers 24 terminating in polygonal heads 25 normally positioned in the lower ends of the holder passages l 8 to form seats for the ends of the tobacco cartridges, as shown on Figure 2. Sleeves 26 extend upwardly from the ends of the ejector member which form continuations of passageways 21 for receiving the screws I6, springs 28 encircling these sleeves and the screws, these springs normally holding the ejector element to the bottom of the bowl.

A boss 29 on the lower side of the ejector member receives and centers an ejector button 30 which is held in place by a screw 3|, this button normally engaging in the opening 32 in the bottom wall I! of the bowl. Upon upward pressure on the button, the ejector element 23 will be shifted against the resistance of the spring 28 to move its plungers 24 through the passageways l8 for ejection from these passageways of the butts or remains of the tobacco cartridges after smoking thereof.

In order that there will be no leakage of air into the suction chamber 20 through the opening 32 during smoking of the pipe, the button 30 is preferably made of'frusto-conical shape to function as a valve for seating against the correspondingly shaped edge of the opening 32, and the button is therefore preferably made of some resilient material such as rubber. As shown on Figure 2, the arrangement is such that the ejector element 23 will not contact the bottom wall I! of the bowl so that the entire force of the spring pressure will be against the valve button 30 to hold it securely against its seat in the opening 32 to efiect a seal against air leakage to the suction chamber 20. In order to provide more extended and secure anchorage for the screws I6, the bowl bottom wall I! may have the bosses 33.

The stem bore -2l may be enlarged as indicated at 34 for receiving a filtering element 35 for filtering the smoke before passage thereof through the stem bore 22. Through the sides of the bowl air inlet holes 36 may be provided for the flow of air into the bowl for insuring more uniform combustion of the tobacco cartridges.

To fill the pipe for smoking, two cartridges I9 are inserted in the cylindrical holder passages l8 to seat against the heads 25 of the ejector plungers 24. Owing to the polygonal form of the plunger heads, there will be ample passageway between the heads and the cylindrical passageways for the application of suction to the cartridges .for smoking thereof, and owing to the adequate air space within the bowl around the cartridges and the air supply through the holes 36, there will be eificient and uniform combustion, the comparatively large air space between .the burning cartridges and the bowl walls insulating these walls against the accumulation of heat, thus assuring a cool smoke. This space in the bowl around the cartridges also serves as .an ash receptacle for receiving the ash from the cartridges. The cartridges are preferably of a length so that when inserted in the pipe they will project only a short distance above the bowl so that they may be more readily ignited, but so that the falling ashes will be caught by the bowl.

With my improved arrangement, where two cartridges are inserted in the pipe and are smoked in parallel, the volume of smoke will be correspondingly multiplied for more enjoyable smoking. The cartridges are in the form of tobacco rolled in and held by a wrapper, preferably of paper, and different brands of ordinary smoking tobacco may be used which, after a comparatively short period of non-operation of the pipe, will automatically extinguish so that,

the pipe'may be relit at any time forccntinued or final smoking of the cartridges until they are fully consumed.

The cartridges may be of ordinary cigarette diameter but of half cigarette length so that they .may be readily commercialized in packages of the same size as ordinary cigarette packages.

I have shown a practical embodiment of the features of my invention but I do not desire to be limited to the exact construction, arrangement and operation shown and described as changes and modifications may be made without departing from the scope of the invention,
